Tannage Résumé : A unique potentiator chemistry has been developed which enhances leather fungicide performance for both chrome and vegetable tanned wet leather stock mold control. Potentiators function by increasing the penetration of fungicides into fungi by way of increased attachment, distribution and adsorption of the active ingredient on the fungal organisms. In this way, the potential of the fungicide to control and inhibit mold growth can be enhanced significantly. This paper will review the theory and application of potentiation chemistry and will review laboratory and tannery experience where potentiators have been utilized to enhance fungicide effectiveness in wet leather stock.

Fungicides in military leather : an additional option for tanners producing specification leathers / Dean Didato in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. XCIV, N° 7 (09/1999)

Tannage Résumé : For several decades, paranitrophenol (PNP) has been specified for use in the manufacture of U.S. military leather items. However, PNP lacks the essential U.S. Environmental Protection Agency registration for such use. Supplies of PNP are tightly controlled by the manufacturer, and are only released upon receipt of a Department of Defense (DOD) contract number. The inherent problem for the tanner lies in the trace PNP that appears in the process effluent and in solid wastes (shavings and trimmings). Environmental, regulatory compliance, and worker health issues have compelled the industry to seek replacements for paranitrophenol. Several alternative fungicides are included in military specification MIL-PRF-3122H as well as the forthcoming MIL-PRF-3122I. However, performance data relative to the use of these alternatives has not been published, nor is it readily available. The authors of this paper will share the results of recent testing to determine the feasibility of an U.S.E.P.A.-registered formulation of 2-(thiocyanomethyl-thio)benzothiazole (TCMTB) in military specification shoe upper leather as a PNP replacement. These studies were undertaken with the guidance of the U.S. Army Natick Research, Development, and Engineering Center (NRDEC). Testing began with Federal Test Method Standard No. 191A, Method 5762, entitled “Mildew Resistance of Textile Materials - Soil Burial Method”, and was followed by the standard test method for the Slit Tear Resistance of Leather (ASTM D2212) as well as environmental chamber testing.
